Description
Technical field
The present invention relates to a kind of alarm valve station for fire alarm system, the alarm valve station has：Alarm valve, especially
There is fire-extinguishing fluid entrance and fire-extinguishing fluid to export for wet alarm valve, the alarm valve, and wherein alarm valve is designed for：Selectivity
Ground discharges or is blocked in the fire-extinguishing fluid stream between fire-extinguishing fluid entrance and fire-extinguishing fluid outlet；Pressure sensor, the pressure
Sensor is connect in a manner of conducting fluid with alarm valve, and is designed for：Detection pressure change and the report for being transformed into electricity
Alert signal；With presignal delay device, it to be used for delayed alarm signal.
The invention further relates to a kind of fire alarm system with this alarm valve station and a kind of fire extinguishing systems.
Background technology
The fire-extinguishing fluid entrance of the alarm valve at this alarm valve station is supplied usually in a manner of conducting fluid with fire-extinguishing fluid
Device connects.The fire-extinguishing fluid of the alarm valve at this alarm valve station, which exports, to be connected usually in a manner of conducting fluid with applicator device
It connects.There is fire-extinguishing fluid stream by triggering one or more sprinklers connected, the fire-extinguishing fluid stream is by means of alarm valve
(passively) discharge, as long as and then alarm valve preferably have for for example to the closed state of valve, alarm channel (valve) in
Pressure etc. carries out the one or more sensors of state-detection, just can also detect the fire-extinguishing fluid stream.
When flowing alarm valve, within alarm valve and in the fluid line being connect with alarm valve in a manner of conducting fluid
And/or there is pressure change in the alarm circuit of branch.In known alarm valve station, the pressure change is passed by means of pressure
Sensor detects and is transformed into the alarm signal of electricity, and the pressure sensor is connect in a manner of conducting fluid with alarm valve.
However, pressure change can not only occur in the case where triggering sprinkler.In practice it has been confirmed that：It goes out
Fiery fluid supply apparatus also is subjected to pressure oscillation, such as the compression shock within water supply pressure because of variation or water supply network
Caused by pressure oscillation.Therefore this pressure oscillation of fire-extinguishing fluid feeding mechanism can cause to generate by the of short duration of alarm valve
Flow so that cause by pressure sensor generate electricity (mistake) alarm signal.
It is redirect in order to avoid this false alarm：The delay container of hydraulic pressure is connected in pressure sensor upstream.It is pressing
In the case that power rises, before pressure sensor can detect pressure change, the delay of hydraulic pressure is filled with fire-extinguishing fluid first
Container.According to the design scheme of the delay container of hydraulic pressure, the filling process until several minutes can be required.Therefore, it is flowed in fire extinguishing
In the case of the pressure oscillation of body feeding mechanism, it can detect pressure change in pressure sensor and be transformed into the alarm signal of electricity
Before number, it is first begin to the filling of delay container.However, the pressure oscillation of fire-extinguishing fluid feeding mechanism usually only continues several seconds,
So that only there is the slight filling of delay container, and then pressure sensor does not detect pressure change.Therefore, electricity is not generated
Alarm signal so that prevent through false alarm caused by the delay container of hydraulic pressure.
However, the use of the delay container of hydraulic pressure is associated with some disadvantages.Thus, for example by the pressure in water supply
Relationship and container size pre-set delay sustained periods of time, and subsequently can not be easily in the case where no replacement postpones container
Change.In addition, delay container is the hydraulic component of security-critical, and thereby result in high manufacture and maintenance cost.In addition, liquid
The delay container of pressure occupies the big structure space at alarm valve station, this especially limits in the case where spatial relationship is narrow and can apply
Property.
Finally, the delay container of hydraulic pressure needs the circuit being attached to be arranged to so that fire-extinguishing fluid is after operation
Again automatically from the feasibility in delay container, pressure sensor and alarm circuit outflow, the structure of this limitation implementation.
Invention content
Therefore, the purpose of the present invention is to provide following solution, by the solution can with it is simpler, with
And preferably space-saving ways and means and implement presignal delay under the conditions of manufacture and maintenance cost are smaller, and
Further preferably delay time can be preferably matched with desired value in the solution.
The purpose that the present invention is based on proposes that the alarm valve station of type is realized by starting, wherein presignal delay device structure
